CTS Turbo High-Flow Cats are made to maximize exhaust flow for the highest power gains. Do not compromise performance and sound with factory parts. Designed using the latest in CAD technology; this part is made to fit perfectly in place of the restrictive factory catalytic converter. Manufactured from CAST T304 stainless steel; hand TIG welded and back-purged to ensure years of reliable performance. In addition to unleashing the power and performance of your 4.4 Twin Turbo, CTS' High-Flow Cats will make your vehicle sound like it really should. When installed with factory exhaust it produces a louder and deeper growl with a much more pronounced exhaust “crackle” on downshift. While up-shifting you will enjoy a confident “punch!” as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system. Product Details: Includes 200 cell sport catalytic converter Designed and tested on a real car in the real world Cast T304 stainless steel, TIG welded back-purged construction Replaces restrictive factory catalytic converter Great power upgrade with uncompromising performance Incredible sporty exhaust sound, subtle when cruising No drone with factory exhaust Fitment: 2018-2021 F90 BMW M5 2018-2021 F90 BMW M5 Competition 2020-2021 F91/92/93 M8 To remove the CEL that will occur, proper stage 2 tuning software must be used.

CTS Turbo is proud to release the S63TU/N63TU 4.4L intake which is a complete replacement for the OEM system. The design intent was to create the largest, highest flowing intake on the market. Features a massive 6' velocity stack air filter and a 3' aluminum intake pipe that connects perfectly to the turbo inlet. An extra turbo heatshield is included in order to keep air intake temperatures as low as possible. Without any extra tuning, peak power gains range from 12 to 20HP (fuel and elevation dependent). All of the components included in the CTS air intake system work flawlessly together to provide increased horsepower and torque throughout the entire power band and an aggressive race-inspired sound. Features: Massive velocity stack reusable air filter 3' smooth air intake pipe Black powder coat for OEM look Great sound and power increase Affordable price without sacrificing quality
